DSPENSING-FAUCET.

Specification of Letters Patent. n

Patented May 1, 1909.

To all Iwhom t may concern:

Be it known that I, EDWARD E. li/lURPI-IY, a citizen of the United States, residing in lVinchester, in the county of Middlesex and State of Massachusetts, have invented an lmprovement in Dispensing Faucets, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The present invention relates to a dispensing faucet, and is embodied in a faucet of that class which is used in dispensing carbonated beverages, in which a large outlet nozzle and a small outlet nozzle are employed for mixing purposes.

In accordance with the invention, the faucet is so arranged that the movement of .an g actuating handle to two different positions in the same direction will open the nozzles respectively, both nozzles being closed when the handle is in its normal position, the valve being preferably provided with a spring whereby it is self closing.

Tn accordance with the invention, the main or large nozzle is connected directly with the valve chamber which is provided with a lateral inlet and with a longitudit nally movable tubular valve provided with lateral inlets and packing toprevent the liquid from leaking around said valve. small outlet is connected with a supplemental chamber within the large outlet or nozzle, communication between this supplemental chamber and the valve casing being opened by a longitudinal movement of the valve member. The supplemental casing is provided with' comparatively large ports through which Vthe liquid can flow to the main nozzle, the construction being such that a complete movement of the valve closes these ports, allowing communication only directly through the small nozzle.

In accordance with the construction, the tubular valve in its first downward movement opens the ports, allowing the liquid to flow into the supplemental chamber, and thence through the outlets to the main nozzle. A further movement of the valve brings the end of the tubular portion thereof to a. seat upon a washer located below the ports in the supplemental chamber, the4 small nozzle opening through the said seat, so that the liquid is free to escape therefrom, but has no other outlet.

The

the handle 70 is released.v

Figure 1 is a vertical section of a faucet view showing the faucet open to a position to allow the iuid to pass through the large nozzle; and Fig. 3 is a similarview showing the position in which the large nozzle is closed and only the small nozzle is open.

The valve casing a which is provided with a lateral inlet a2, is shown as provided with an arm or extension a3 to support a pivotally connected handle connected at b2 with a tubular valve member c which projects into the valve casing a. At opposite sides of the inlet a2, the valve member c is surrounded by cup leather packings d and d2, the upper packing being held in position by means of a packing gland e, there being also a washer c2 between the packing and the gland to afford a'seat for a spring f, the upper end of which bears against a shoulder c2 formed on the valve member c.

As will be seen from the drawings, a downward movement of the valve member c causesthe spring to be compressed, so that the said spring tends to restore the valve to its normal position shown in Fig. 1 when Below the lower packing l? the valvechamber is .provided with a main large nozzle at which is shown as screwed into the lower end of the -casing a, and abutting against the flangev g2 of a supplemental chamber' member g, which is provided with a small nozzle g3, and with comparatively large outlets or ports got. The flange g2 bears against the lower surface of the cupy leather packing cl2, and in connection with the nozzle member a4 affords a packing gland to keep the valve member c tight. The said valve member 0 is provided with Va longitudinal port c3 having a series l of 'lateral inlets c4 which normally stand above the upper packing member 0l so that the valve chamber is closed by the main wall of the tubular valve. On moving said tubular valve downward, however, the said ports c4 are brought into communication with the valve chamber, thus allowing the liquid to flow into the tubular portion c3. A downward movement of the valve c, therefore, to the extent illustrated in Fig. 2, will open communication between the valve chamber and the tubular portion of the valve c, allowing the liquid to flow into the supplemental chamber g, and thence through the large, lateral ports g4 to the main nozzle a",

thus supplying the said main nozzle with a suiiiciently large volume of liquid to attain the desired result. rlhe supplemental nozzle g3 which opens through the bottom of the chamber g will also supply some of the liquid, the said nozzle being opened at this period. l'n order to cut oiip the supply from the large nozzle a and to allow the liquid to flow only through the small nozzle g3, the device is so arranged that a further movement of the valve c will close communication between the tubular portion thereof and the outlets g4, thus allowing the liquid to escape only through the small nozzle g3. For this purpose the chamber g is provided at its lower end with a valve seat or washer g5 against which the end of the valve member C is brought to bear when the valve is moved to the position shown in Fig. 3. rlhis closes communication between the valve member c and the ports g4, so that the only path of escape for the liquid is through the small nozzle g3.

Since the main source of supply through the valve inlet a2 is the same for the large and the small nozzles, it is necessary to throttle the small nozzle g3 to whatever eX- tent is desired, and it may be desirable to aiford means for varying the capacity of the said small nozzle. F or this purpose, the lower end of the chamber member g above the port which forms the small nozzle may be provided with a screw threaded cup portion g@ adapted to receive a screw g having a small longitudinal slot g8. The capacity of the small outlet, therefore, can be varied by turning the screw to expose more or less of the slot above the top of the cup-portion gg.

Claims.

l. ln a dispensing faucet, a valve chamberprovided with a lateral inlet; a tubular valve member longitudinally movable in said chamber, said valve member being packed at opposite ends and provided with lateral ports; a supplemental valve chamber below the main valve chamber, and provided with a small nozzle and relatively large outlets above said nozzle; and a valve seat at the bottom of said supplemental valve member to cooperate with the end of the tubular valve member and close the relatively large outlets, substantially as described.

2. In a dispensing faucet, a valve chamber having upper and lower portions; a tubular valve movable in said valve chamber and provided with cut-leather packings, one of said packings being between the upper and iower portions of the valve chamber; a small outlet nozzle opening through the lower portion of the valve chamber which is provided with relatively large outlets above said nozzle; and a valve seat surrounding said nozzle and adapted to cooperate with said tubular valve member to close the relatively large outlets.

3. The combination with a longitudinally movable tubular valve member open at one end and provided withy lateral inlets; of a valve chamber having a lateral inlet and being provided with cup-leather paclzings for said tubular valve member; a supplemental chamber below said valve member provided at the bottom with a small outlet nozzle, and at the sides with relatively large outlet openings; a valve seat surrounding the nozzle at the bottom of said chamber; and means for varying the capacity of said nozzle.

4t. In a dispensing faucet, the combination with a casing; provided with a lateral inlet and a supporting arm; of an actuating handle pivotally connected with said supporting` arm; a tubular valve member projecting through said casing and connected with said actuating handle; a cup-leather packing surrounding the upper end of said tubular member; a spring located between said packing and a shoulder formed on said tubular member; a supplemental chamber portion located below the end of said tubular valve member; a cup-leather packing above said supplemental chamber portion; a large nozzle member extending into the casing and holding said supplemental cham ber and said cup-leather packing in position; and a small nozzle within the large nozzle connected with said supplemental chamber which is also provided with a valve seat around said nozzle and with lateral outlets above the same.

In testimony whereof, l have signed my name to this specification in the presence of two subscribing witnesses.
